My Layman's reloading manual says brass is good for 6-15 reloads. It's harder to determine the number of reloads with the 9mm brass since I have a mix of my brass and range brass (hard to tell which is mine on the floor mixed with others). So do you just carefully inspect the brass or just toss after a half dozen or so reloads? Headstamps, I'm reading in some sites that you should sort your 9mm brass by headstamp, the Layman's manual has good info on pistol brass, but doesn't mention a thing about sorting by headstamp. Is this really necessary for the 9mm? I don't do it for my revolvers. Some of the brass had been stepped on and was deformed at the mouth some. The sizing die fixed most of it. But a few pieces while looking fixed have a shiny triangle on the outside of the brass where the indentation was. I'm guessing I should toss those, along with the ones that were heavily dented to start with.
